Denver was made green on purpose. Water was walked in from the mountains through ditches dug by hand, and the City Ditch still slips quietly through Washington Park, feeding a century of lawns that had no business existing on a semi-arid plain. Archer-Healy Lawn Sprinklers carries on that argument with the climate — keeping turf even and living through July, when the sun is fierce, the humidity is nowhere, and a lawn can go from deep green to straw in the space of a bad week. The work is mowing and trimming and reading a yard closely enough to know which corner is drying out before it browns. Around here, a lawn that holds its color into August is not luck; it's attention, paid all summer long.
